Abstract

A process for preparing a difluoro chelato borate salt comprising an anion A of formula (I) wherein is a bidentate radical derived from a 1,2-, 1,3- or 1,4-diol, from a 1,2-, 1,3- or 1,4-dicarboxylic acid or from a 1,2-, 1,3- or 1,4-hydroxycarboxylic acid by abstracting the two H atoms of pairs of adjacent OH groups of the respective diol, hydroxycarboxylic acid or dicarboxylic acid. The process includes step (i) reacting (a) one or more BF3 sources; (b) a dihydric compound selected from 1,2-, 1,3- and 1,4-diols, 1,2-, 1,3- and 1,4-dicarboxylic acids, and 1,2-, 1,3- and 1,4-hydroxycarboxylic acids; (c) one or more second boron sources which do not contain F; and (d) one or more proton acceptors.
